php - 如何将输入值转换为会话变量？

Question

我只想知道如何将输入值（例如电子邮件）转换为会话

Answer 1

session_start(); // at the beginning of your code.
$_SESSION['email'] = $email; // if the variable already initiated.




$_SESSION['email'] = $_POST['email']; // coming from HTML FORM with method = POST
$_SESSION['email'] = $_GET['email']; // coming from HTML FORM with method = GET

然后，转到另一个 php 文件并执行此操作

session_start();
$email = $_SESSION['email'];

如果您需要随时销毁会话。你需要取消设置会话

unset($_SESSION['email']);

Answer 2

session_start();

$_SESSION['email'] = $_POST['email'];

或者

$_SESSION['email'] = $_GET['email'];

或者

$_SESSION['email'] = $_REQUEST['email'];

Answer 3

看起来你需要给自己买一本好的 php 书，并阅读大量内容。

只是为了让您朝着正确的方向前进，首先，输入将在 $_GET 或 $_POST 超全局变量中可用，请参阅：

• http://www.php.net/manual/en/reserved.variables.get.php
• http://www.php.net/manual/en/reserved.variables.post.php

其次，确保您需要写入会话或从会话读取的每个页面都有 session_start() 调用： http: //php.net/manual/en/function.session-start.php

最后，会话变量可通过 $_SESSION 超全局变量获得：http ://www.php.net/manual/en/reserved.variables.session.php 。

因此，此时，您可以将输入写入会话，如下所示：

session_start();
$_SESSION['email'] = $_GET['email']; // assuming your email came in a GET request

在另一个页面中，您可以像这样读取会话变量：

session_start();
$local_variable_email = $_SESSION['email'];

Answer 4

您的输入类型：

<input type="text" name="email" />

然后

session_start();
$_SESSION['email'] = $emailvariable;  
$emailvariable = $_POST['email'];

  //email is the name you assigned in your input type. 
  //emailvariable is any variable you want to assign.   

在你的不同页面

session_start();
$emailvariable = $_SESSION['email']

Answer 5

  session_start();  
if(isset($_POST['email']){
  $_SESSION['email'] = $_POST['email'];
}

OR
if(isset($_GET['email']){
  $_SESSION['email'] = $_GET['email'];
}
OR

if(isset($_REQUEST['email']){
  $_SESSION['email'] = $_REQUEST['email'];
}
